System of Particles and Rotational Motion | Complete Class 11 Physics Revision

This lesson explains how a collection of particles moves as a system and how rotation works in physics. It covers centre of mass, momentum of a system, torque, angular momentum, moment of inertia, radius of gyration, and the laws of rotational motion. The chapter also includes important theorems like parallel axis theorem and perpendicular axis theorem, along with rolling motion and equilibrium of rigid bodies. It is a very important chapter because it connects linear motion with rotational motion and is full of formula-based and concept-based questions
